ordinary plugs will do provided that they are the correct reach ( length of thread) platinum plugs will out last the engine but you have to consider the cost as they are around 4 times the price of normal plugs One thing you should know about the modern plug is that unless they develop a misfire with the modern ECM engines they very rarely need changing Unlike plugs in the old fashioned points in a distributor type engine I personally have used the same plugs from new to disposal , 12 years later and at 230.000klms and misfire from plugs was never an issue.

Could be a bad coolant temperature sender.Here's a link on how to test it. http://www.autozone.com/repairinfo/repairguide/repairGuideContent.jsp?fromSearchPage=true&pageId=0996b43f80376229&partName=Coolant+Temperature+Sensor&partId=0996b43f80376229

The suggested answer here about a bad electrical ground is a possibility, as gauges and senders do depend on good ground return. Given that your cooling system was worked on, it is possible you have a big bubble in the coolant system which means it has not got all the capacity it should. Go park nose up on the steepest hill where the handbrake will hold, let it cool down until you can safely remove the radiator cap, open the heater control fully, and idle the engine until it is at normal operating temp. If you see the level drop, it had a bubble in it. You might also want to have it tested for combustion gases getting in the coolant via a slightly leaky head gasket. https://www.youtube.com/watch?v=a3J00_e7fyo
